[0003] It is known to provide an aerosol-generating device for generating an inhalable vapor. Such devices may heat aerosol-forming substrate to a temperature at which one or more components of the aerosol-forming substrate are volatilised without burning the aerosolforming substrate. Aerosol-forming substrate may be provided as part of an aerosol-generating article. The aerosol-generating article may have a rod shape for insertion of the aerosolgenerating article into a cavity, such as a heating chamber, of the aerosol-generating device. A heating element may be arranged in or around the heating chamber for heating the aerosolforming substrate once the aerosol-generating article is inserted into the heating chamber of the aerosol-generating device.
[0004] Articles for an inhaler, such as for a dry powder inhaler may have a component for storing dry powder, such as a capsule. The capsule may be located within a substrate portion of the article. The capsule can be activated by being pierced by a separate piercing element. Once the capsule has been activated, or pierced, a consumer may use the inhaler article by drawing on the mouth end (downstream end or proximal end) of the inhaler to generate an air flow through the inhaler. As air flows through the inhaler article, the capsule rotates about itself inside the substrate portion of the inhaler article. The agitation of the capsule and the air flow pressure causes the release of dry powder from the pierced capsule. The released dry powder is carried by the air flow to the mouth of a user. The article may comprise a support member that retains the capsule in the substrate portion before piercing, during piercing, after piercing, and during use.
[0005] Articles are often manipulated before and during use. For example, the articles may be subjected to longitudinal and radial pressures as they are manufactured, packaged, unpackaged, inserted into devices, activated, used and discarded. Articles are not always fully suitable to withstand this manipulation.

As an alternative, the power supply may be another form of charge storage device such as a capacitor. The power supply may require recharging and may have a capacity that enables to store enough energy for one or more usage experiences; for example, the power supply may have sufficient capacity to continuously generate aerosol for a period of around six minutes or for a period of a multiple of six minutes. In another example, the power supply may have sufficient capacity to provide a predetermined number of puffs or discrete activations of the heating element.
[0158] The aerosol-generating article may be inserted into a cavity of the aerosol-generating device. The cavity of the aerosol-generating device may have an open end into which the aerosol-generating article is inserted. The open end may be a proximal end. The cavity may have a closed end opposite the open end. The closed end may be the base of the cavity. The closed end may be closed except for the provision of air apertures arranged in the base. The base of the cavity may be flat. The base of the cavity may be circular. The base of the cavity may be arranged upstream of the cavity. The open end may be arranged downstream of the cavity.

Downstream of the cavity, a mouthpiece may be arranged or a user may directly draw on the aerosol-generating article. The airflow channel may extend through the mouthpiece.
[0162] The aerosol-generating device may comprise a heater assembly. The heater assembly may comprise a heating element. The heating element of the heater assembly may comprise an electrically resistive material. Suitable electrically resistive materials include but are not limited to: semiconductors such as doped ceramics, electrically "conductive" ceramics (such as, for example, molybdenum disilicide), carbon, graphite, metals, metal alloys and composite materials made of a ceramic material and a metallic material.
[0163] The heating element may be part of an aerosol-generating device. The aerosolgenerating device may comprise an internal heating element or an external heating element, or both internal and external heating elements, where "internal" and "external" refer to the aerosol-forming substrate.
[0164] As an alternative to an electrically resistive heating element, the heater assembly may be an inductive heater assembly. The heating element may be configured as an induction heating element. The induction heater assembly may comprise an induction coil. The induction coil may be configured to heat the susceptor element of the aerosol-generating article. The induction coil may be configured to heat the heating element. A susceptor element may comprise a material that is capable of generating heat, when penetrated by an alternating magnetic field when located in an alternating magnetic field. If the susceptor element is conductive, then typically eddy currents are induced by the alternating magnetic field. If the susceptor element is magnetic, then typically another effect that contributes to the heating is commonly referred to hysteresis losses. Hysteresis losses occur mainly due to the movement of the magnetic domain blocks within the susceptor element, because the magnetic orientation of these will align with the magnetic induction field, which alternates. Another effect contributing to the hysteresis loss is when the magnetic domains will grow or shrink within the susceptor element. Commonly all these changes in the susceptor element that happen on a nano-scale or below are referred to as “hysteresis losses”, because they produce heat in the susceptor element. Hence, if the susceptor element is both magnetic and electrically conductive, both hysteresis losses and the generation of eddy currents will contribute to the heating of the susceptor element. If the susceptor element is magnetic, but not conductive, then hysteresis losses will be the only means by which the susceptor element will heat, when penetrated by an alternating magnetic field. The susceptor element may be electrically conductive or magnetic or both electrically conductive and magnetic. An alternating magnetic field generated by one or several induction coils heat the susceptor element, which then transfers the heat to the aerosol-forming substrate, such that an aerosol is formed. The heat transfer may be mainly by conduction of heat. Such a transfer of heat is best, if the susceptor element is in close thermal contact with the aerosol-forming substrate.
